Abstract: A spark plug wire puller is described which is actuated by a user squeezing a trigger biased against a handle of the tool which causes two jaw members to come together at gripping ends thereof to squeeze a wire or boot. As the user squeezes the trigger and pulls on the tool, the jaws grip the wire or boot and remove it from the spark plug. The invention is advantageous because it does not rely on a scissors action and it grips the boot in such a way so as not to damage it during the removal process.

Abstract: A hand held electrical circuit testing for use by technicians to determine circuit conditions such as, whether a duty cycle is present or whether constant voltage is present. The invention makes use of three visual indicating means within a clear body portion of the device which reveal a lighting pattern that will provide an experienced technician with information to determine the circuit condition.

Abstract: A handle linkage including two handle arms rotatably secured to each other, while one handle arm is attached to the body of a tool and the other handle arm is attached to an actuatable member of the tool. One or more links connect the actuatable member to the second handle arm allowing for substantially linear movement of the actuatable member into the body of the tool.

Abstract: A socket wrench is shown having a socket driver head pinned to a clevis on a shaft. A sleeve is receivable over the shaft end and includes open ended slots pointing away from the clevis. The shaft includes a pin press fit within a cross bore on the shaft end, and the shaft and sleeve are axially slidable relative to each other; where in one position the pin engages one of the slots, and in another position, the shaft and sleeve spin freely of each other. A handle includes an internal bore which is profiled to compressively fit over the sleeve, and a chamber is defined between the sleeve and the end of the internal bore, to provide clearance for the axial movement of the shaft and sleeve.

Abstract: A device for testing the polarity of both a power supply and a test element such as a circuit, wire or the like. The device is comprised of a body which contains a circuit board, a probe extending from one end of the body, and two lead wires extending from the opposite end of the body. The device will work on any DC voltage supply having a voltage from 6 volts to 24 volts.

Abstract: An improved drawer front assembly for attachment to drawers commonly found in tool boxes and the like. The drawer fronts are removable and replaceable and are attached to the drawers by means other than welding. The fastener means are concealed from view and from touch from outside the drawer. The invention allows for various materials and/or colors and/or styles of drawer fronts to be installed on drawers of tool boxes and the like without substantially altering the traditional tool box/drawer design.

Abstract: In an auxiliary starter switch device, a guard for the auxiliary switch actuator and a small warning lamp and lens are combined in such a way that the guard itself contributes to the indicator warning. The guard is formed of a transparent or translucent material, and the lamp and lens (or an equivalent LED) is mounted in optically close-coupled arrangement with the guard. When the lamp is energized, the guard itself is substantially illuminated to expand the warning light area.

Abstract: A universal joint for use with impact wrenches and the like comprising a coupling having a bore at one end for engaging the drive shaft of a wrench and a ball receiving cavity at its other end; a socket engaging part having a ball member disposed in the ball receiving cavity; and a guide sleeve concentrically and slidably mounted for free rotation to the coupling, the guide sleeve having a substantially smooth uninterrupted outer cylindrical surface which may be held between the fingers of an operator while the joint is rotating.
